> An F-15 being shot down in Iran after weeks of strategic bombing of their anti-air defense systems is not a good sign.
Not to dispute that but what about the comparison makes it not a good sign? Iran has much more capable radar and missiles now than Iraq did 35 years ago, doesn't it?
The success of the war depends on the approval ratings of the US president which will almost certainly take hits when US military takes hits so the US citizens seeing the US military taking hits at a higher rate than relatively recent wars in the area is a bad sign for "winning" whatever "winning" means here.
